Stochastic Oscillator
Compare closing price to its range over a set period for momentum signals.
What is the Stochastic Oscillator?
The Stochastic Oscillator is a momentum indicator that compares a security's closing price to its price range over a given period. Developed by George Lane in the 1950s, it operates on the principle that in an uptrend, prices tend to close near the high of the range, and in a downtrend, near the low. It produces two lines: %K (the main line) and %D (a moving average of %K).
How It Works
The Fast Stochastic uses raw %K and its simple moving average as %D. The Full (or Slow) Stochastic applies additional smoothing to reduce noise. %K is calculated as: (Current Close − Lowest Low) / (Highest High − Lowest Low) × 100. Readings above 80 suggest overbought conditions; below 20 suggest oversold. Crossovers between %K and %D generate buy and sell signals.
How StockSkier Uses It
StockSkier uses the Full Stochastic Oscillator with a 14-period %K for its entry scoring engine. Stochastic signals contribute to the weighted entry score alongside RSI and MACD. For intraday exits, a stochastic overbought cross-down (the %K crossing below %D while both are above 80) is one of the confirmation conditions required before the model will exit a profitable position.
Key Takeaways
- ✓%K measures where the close falls within the recent high-low range
- ✓Above 80 is overbought; below 20 is oversold
- ✓Full Stochastic adds smoothing to reduce false signals
- ✓Crossovers between %K and %D generate trade signals
- ✓StockSkier uses stochastic as part of multi-indicator confluence scoring
